Design outcomes
Secondary
| Measure | Time frame |

| The measurements of respiratory induction plethysmography as well as clinical signs of airway obstruction will be recorded, as obtained at the various levels of airway obstruction. | — |
Primary
| Measure | Time frame |
|---|---|
| The measurements of the inertial sensors will be related to the measured tidal volumes and airway pressures, as obtained at the various levels of airway obstruction. | — |
